UMBRELLA-LOCK.

SPEGIFIcATIoN forming part of Letters Patent No. 674,390, dated May 21,1901.

Application iled May Z3, 190D- To all whom it may concern:

Be it known that I, THEoDoRE J. ZOELLER, a citizen of the United States,residing at Nashville, in the county of Davidson, State of Tennessee,have invented certain new and useful Improvements in Umbrella- Locks;and I hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanying sdrawings, in which- Figure l is a view, partly in section, of anumbrella lock embodying my invention shown in connection with anumbrella-handle and the lower portion of the umbrella rod and ribs. Fig.2 is an under side View of the toothed disk or rib-rack, the lockingtube orf Fig. 3 is a detached view" of the body-tube or arbor whichcarries the toothed disk or rib-rack and the tumbler-disks of the lock.Fig. 4is a detail View, partly in section, of the arbor or i body-tube,the tumbler-disks, springs, ferrules, and click, one of thetumbler-disks being omitted for sake of clearness and the outer shell orcasing shownin dotted lines. Fig. 5 is a detached sectional View of theouter shell or casing. Fig. 6 is anlend View of the outer shell orcasing. Fig. 7 is a top view of the ferrule with click in position. Fig.8

is a detached view of the click. Fig. 9 is a plan view of one of thetumbler-disks, the

dotted radial lines indicating divisions of the disk and showing therelation of the slots or notches to the pins forming the combination ofthe lock. On this figure other positions of the pin for differentcombinations are indicated by dotted lines. Fig. l0 is an edge elevationof the tumbler-disk shown in Fig.

9. Fig. ll is a plan View of a curved spring-k washer used inconjunctionwith the tumbler-disks. Fig. 12 is a View'of a split or spring ring forholding the tumbler-disk and spring-washer in position on the body-tubeor arbor.

. Like symbols refer to like parts wherever they occur.

My invention relates to the construction of locks especially applicablefor securing an umbrellain a closed position to prevent unauthorized usethereof, and belongs generally to the class of devices known aspermutation-locks, wherein are combined a casing and series ofcombination-tumblers, together with means for operating the tumblers,and a serai 110.17.746. oto man.; s,

bolt or like means,the longitudinal movement whereof is controlled bythe position of the` tumblers. n l

In carrying out my invention I combine with a plurality of includedrotatable disks having slots and pins an inclosing shellvor'casinghaving on its interior alug or lugs adapted to operate the disks andalsol to pass through the slots of the disks, the disks being adaptedwith the tumbler-,disks 'and the outer shelll to operate one the otherin succession, the 'y adapted to operate said disks and'to move llongitudinally thereofto-secure orrelease'u'rna l A 75'.'

brella-ri bs or like devices, forms a secondl feature of my invention. Y

There are other'minor combinations and p "y details of'construction`constitutingr further features of my invention, all `as will herein v8oart to which it appertains may apply the same:r

In the drawings, l indicates a tubular arbor or tube-body (adapted tobesecured on an umbrella-rod R) having a seriesof annular grooves 1L forthe reception of springrings 2,

which hold the tumbler-disks 3y and' springf i washers 4 in properrelative position on said central shell or arbor l. Formed on or securedto the npperend of said tube-body or tubular arbor l is a notched orserrateddisk 5, adapted to receive the lower ends of the umbrella-ribsR, which ends may have the usual protuberances or be otherwise formed,so as to be securely held by the said toothed or notched disk 5 when thesliding casing or outer shell of the lock incloses said disk 5'. Securedon the tube-body or larbor l a short distance below the toothed disk 5andfabove the position of the upper tumbler-disk 3 is a second plaindisk 6, which not only serves to limit thevlongitudinal movement of theouter shell or casing 7, but also to close said casing against theadmission of dust anddirt, thus protecting the tumbler-disks 3 3. 3 3indicate a plurality of tu mbler-disks carried by IOO said tube-body orarbor l., each of said disks provided at its periphery with notches orslots 3 and at some point on its faces with pins 3b 3b. A single slot ornotch 3 will suffice for each disk; but I prefer to make at least twosuch notches, which may be located almost diametrically opposite eachother, as thereby the tumbler is supported against tilting or binding incase undue strain is applied in an attempt to force the lock. As theslots 3 and pins 3b must bear a relative posi'tion for the purposes ofany given com bination, the faces of the tumbler-disks and the interiorof the outer shell or casingare divided into a certain number of equalspaces, and for the purposes of illustration I have selected ten as thenumber, the same being indicated as to the tumbler-disks by the dottedradial lines on Fig. 9 of the drawings and as to the outer shell or casebythe notches seen in Figs. 5 and 6of the drawings. These tumbler-disksmay be formed in any suitable manner, preferably by stamping the samefrom sheet metal, in which case the pins 3h 3b will be struck from thebody of the metal of a given space and the pins of the opposite faceswill stand at the opposite edges of said space. In case, however, solidpins are used they will be equalin width to the space they occupy, asindicated in dotted line p, Fig. 9. As shown in full line, Fig. 9, thepins of the tumbler-disk are located at some distance within theperiphery of the disk, which is the construction for the coacting disksofthe series; but the tumbler? disk which is to be operated directly bythe lug or lugs on the interior of the outer shell or casing 7 must havea pin adjacent to its periphery, as indicated by the dotted lines 3C,Fig. 9.

4 4 indicate springs, preferably in the form of curved or bentspring-washers, which are interposed between the tumbler-disks 3 3, and2 2 indicate split or spring rings which serve to secure thetumbler-disks and springwashers in posit-ion on the tubular body orarborl.

7 indicates the outer shell or casing, which incloses the tubular bodyor arbor l and tumbler-disks 3 3 and is longitudinally movable thereon,so as to either cover or uncover the toothed disk 5, according to theposition of the casing 7. Upon the interior of said outer shell orcasing 7 and in position (or spaced) to correspond with the slots of thetumblerdisks are a series of lugs or pins 7iL in number correspondingwith the number of slotsin the tumbler-disks and the slots in thefel-rule S and of such dimensions as to pass into or through said slotswhen the parts are ina `given position determined by the combination ofthe tumbler-disks. On the interior of the outer shell or casing 7, atits lower end and at regular intervals, are a series of notches 7",which serve as click-notches and divide the interior of the shell intospaces corresponding with the pin-and-slot spaces of the tumbler-disks3. Upon the exterior' of said casing 7a projection 7c (see Figs. l, 4,and tl) orequivalent means may be pro vided for determining the positionand movement of the lockingshell by the sense of touch.

8 indicates a collar or ferrule upon the umbrella-handle Where theumbrella-rod joins the same, said ferrule or collar being of suchdiameter as to enter thelower end ofthe outer shell or casing 7 of thelock and provided with notches or grooves 8a rightly located to receivethe lower lugs'or pins 7a on the interior 'of the outer shell or casingwhen the casing is moved longitudinally to release the toothed disk 5and the umbrella-ribs R. Inclosed within and projecting radially fromsaid ferrule or collar S is a spring-actuated click 9, adapted to engagethe notches 7b on the interior of the outer shell or casing 7 and checkthe shell at regular intervals, so that the extent'of movement of thecasing and tumblerdisks can be accurately determined, and thecombination being known the slots of the tumbler-disks can be made toregister with each other and with the slot in the ferrule 8 to permitthe longitudinal movement of the outer shellor casing 7, which willrelease the lock. The bolt and spring of this click 9 may be separate,it' desired, but are preferably formed integral, as shown in Fig. 8 ofthe drawings.

The several parts constituting the lock being of the general characterhereinbefore pointed out, the same may be assembled by slipping thetumbler-disks 3 3 successively and in series upon the tubular body orarbor l, aspring-washer 4 being interposed between each disk and itsbearing and also a springring 2, which will rest in the annular groovelfL of the arbor, and thus confine and space the tumbler-disks andspring-washers. One skilled in the art Will be able to determine thecombination of the lock by a glance at the tumblerdisks, and havingproperly arranged the same upon the tubular body or arbor l, with thedisk slots or notchesin register, the outer shell or casing 7 may thenbe slipped over the tumbler-disks and the ferrule 8 inserted in thelower end of the lock, with its notches S in register with the notchesof the tumbler-disks, which will complete the lock. In the position lastnoted-4.'. c., the several disleslots in register with each other andwith the slots of the ferrule-the device will be unlocked and the outershell or casing can be slipped down to release or raised to secure theumbrella-ribs, and having been raised to secure the umbrella-ribs theouter shell 7 may be locked by rotating the same and disarranging thetumblers, as is usual for like purposes in perm utation-locks ingeneral.

To unlock the device, the outer shell or casing 7 is revolved until oneof its lugs or pins 7 engages a pin near the periphery o'f one of thetumbler-disks 3, usually the lower disk, (see dotted line 3c, Fig. 9,)which causes said tu mble'r-disk to move with the casing or outer shell7 and in turn by its pin 3b to piek up the next tu mbler-disk, and so onthroughout" the series (according to the number of tuin- IOO bler-disksemployed) until bya proper and determined number of turns or part turnsthe slots inthe several. disks have been brought into register with eachother and with the slots in ferrule 8, which will permit the passage ofthe lugs on'the interior of outer shell or casing 7 and the longitudinalmovement of the outer shell or casing, which releases the umbrella-ribs.

Among the advantages due to my invention are, first, the lock is anextremely simple lock of fewparts not liable to become deranged or to bepicked by manipulation of the outer shell or casing; second, thetumbler-disks cannot be bent or twisted by torsion on the shell in anattempt to pick the lock; third, the outer shell constitutes a casing,bolt, and knob in a single device perfectly adapted to its purpose, and,fourth, owing to the toothed disk and sliding shell or casing theumbrellaribs cannot be released by bunching the ribs and springing theshell or by springing the shell and separating the ribs, theumbrellaribs being held securely against any force less than wouldresult in mutilation of the ribs or lock.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with a plurality of tumbler-disks of an inclosingshell or casing provided with a lug for operating said tumblerdisks saidshell or casing being longitudinally movable with relation to saidtumbler-disks,

substantially as and for the purposes speci-v fied.

2. The combination with a tubular arbor, of a plurality of slottedtumbler-disks, and an outer shell or casing provided on its interiorwith lugs to rotate said tumbler-disks, the lugs on the interior of saidcasing being adapted to pass through the slots of the tumblerdisks,whereby the casing may have a longitudinal movement with relation to thetumbler-disks, substantially as and for the purposes specified.

3. The combination with an outer shell or casing having a series of lugson its interior, of a tubular arbor, and a plurality of slottedtumbler-disks having pins for causing the successive operation of thedisks one from the other, one of said tumbler-disks havinga pin at ornear its periphery for engaging a lug on the interior of the outer shellor casing, substantially as and for the purposes specified.
